Abstract
L'invention concerne les dispositifs de détection d'objets mobiles. Elle se rapporte à un dispositif de détection qui comprend un organe 21 de guidage de lumière et un organe sensible 23. L'objet se déplace parallèlement à l'épaisseur de l'organe de guidage de lumière qui collecte une grande quantité de lumière vers le détecteur 23 et donne ainsi une sensibilité élevée. Application aux appareils de prise de vues et de reprographie.
